OEX Alternator 24V 60A Denso Style DXA4051

The OEX DXA4051 is a new 24V alternator rated at 60 amps and built in a Denso style configuration. It is listed as a single leg alternator with an internal regulator, 78mm pulley outside diameter, AA pulley section, and 167mm mount centre-to-centre, so it is important to compare the mounting and pulley details against the unit being replaced before ordering.

This alternator is supplied under the OEX brand, with the brand positioned around products sourced from original equipment manufacturers and aftermarket suppliers, and made in ISO certified factories. It is backed by a 3 year passenger / 1 year commercial warranty, which gives buyers a clear warranty period to consider alongside the application and matching part number.

The unit is identified as part number DXA4051 and is described as suitable for Denso unit make applications. Key physical checks include the 58mm mount leg thickness, 10mm pivot hole diameter, M8 adjusting hole diameter, and 17mm shaft dimension. Those measurements matter when matching the replacement to the existing alternator, especially where bracket, pulley, or mounting clearance is tight.

Application and Buying Notes

When replacing an alternator, the safest approach is to match the part number, electrical rating, and physical mounting points before purchase. For this unit, the key identifiers are DXA4051, 24V, 60A, Denso style, and single leg mount, along with the 167mm mount centre-to-centre and 78mm pulley outside diameter.

The regulator is internal, so the alternator is intended for applications that use that style of regulation. The pulley is AA section, which means the belt profile also needs to be checked against the vehicle or machine already fitted. If the belt profile, shaft dimension, or pulley diameter do not line up with the existing unit, fitment should be rechecked before installation.

The fitment information supplied includes a range of Caterpillar applications, including 312, 314, 314E, 318, 320GC, 325FL, 420E, 420E-IT, 914G, CP series compactors, CS series compactors, CW34, D3K2 LGP/XP, D4K2 LGP/XP, D5K2 LGP/XP, IT14B, M313D, M314F, M316F, and TH series telehandlers. Even where a model appears in the list, the exact alternator on the machine should still be checked against the measurements and part number.

The listed warranty is 3 year passenger and 1 year commercial. That is useful for purchase planning, but it does not replace a fitment check. Alternators can look similar while differing in mounting leg thickness, pivot hole diameter, or pulley setup, so the practical comparison should always be made against the original unit removed from the vehicle or equipment.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number DXA4051 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

OEX Alternator 24V 60A Denso Style. Part number DXA4051 should be checked first. Listed voltage is 24. Listed output rating is 60. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. Regulator type is Internal. Pulley configuration is AA. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4051, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 24 and output 60 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility using part number DXA4051, the Denso style application, 24V 60A rating, and the listed mounting and pulley measurements before ordering.
